Answer:
y=51 x=8
Step-by-step explanation:
if your in a rush I'll explain later
Y + 4x < 8
y < -4x + 8
2 points that satisfy this are (0,8) and (2,0)....and those happen to be ur x and y intercepts (where the line crosses the x and y axis)
graph...so go ahead and plot ur x and y intercepts (0,8) and (2,0).....ur slope is - 4.....so start at ur y int (0,8) and go down 4 spaces, and to the right 1...plot that point, then go down 4 spaces and to the right 1, then plot that point...keep doing this and u will have ur line...u should have crossed the x axis at (0,2)......ur line will be a dashed line since the problem has no equal sign.... the shading will go below the line because it is less then.
y - 3 > = 1/2x
y > = 1/2x + 3
2 points that satisfy this are : (0,3) and (-6,0)...ur x and y intercepts
graph : plot ur intercepts (0,3) and (-6,0)....u have a slope of 1/2...so start at ur x intercept (-6,0) and go up 1 space, and to the right 2 spaces, plot that point...then go up 1 and to the right 2, plot that point...keep doing this and u will cross the y axis at (0,3)....this line will be a solid line....the shading will go above the line.
Answer:
=-18x^2+78xy-24y^2
Step-by-step explanation:
(-2x+8y)(9x-3y)
-18x^2+6xy+72yx-24y^2
-18x^2+(6xy+72xy)-24y^2
=18x^2+78xy-24y^2
Answer:
The amount paid by each house is $11.25
Step-by-step explanation:
Let the amount paid by each house is $K
Number of neighbors you worked for on Friday = 4
So the amount paid by all of them = 4K
Number of neighbors you worked for on Saturday = 5,
similarly amount paid = 5K
Number of neighbors you worked for on Sunday = 3,
here amount paid = 3K
Also, in total the amount paid = $135
So, Amount paid on {Friday + Saturday +Sunday} = Total Amount
or, 5K + 4K + 3K = $135
or, 12K = 135
⇒K =135/12 = $11.25
So, the amount paid by each house is $11.25
Formula to find the slope:
m = y2-y1 / x2-x1
(4,3); (8,5)
m= 5-3 / 8-4
m = 2/4
m = 1/2
Therefore, the slope of the line that passes through these points is 1/2
